Royal fans took to the comments to share their appreciation for the video - which played out to the uplifting song, 'Oh happy days.'
"I love this video so so much. Archie and Arch are so cute... warm my heart," enthused one fan.
A second said: "Such lovely video with Prince Archie and his parents the Duke and Duchess! He is just sooo adorable!"
"What an amazing memory for Archie to have to look back on! Thank you for sharing this with us!" said another follower.
The royals have been on a 10-day tour of Africa, their first royal engagements as a family of three.
With such a packed agenda, the Duke and Duchess of Sussex split their engagements, both taking on separate visits during the tour.
The family spent their first three days together in Cape Town, before Harry left for visits to Botswana, Angola and Malawi.
They have since been reunited in Johannesburg before they head back to the UK on October 2.
